Birds Attacking Windows

When a territorial bird, such as the American Robin or Northern Cardinal, accidentally sees its image in a reflective surface such as a window, it perceives its reflection as a rival in its territory and it tries to drive the other bird away. Their breeding season may total seven or eight weeks; and the "window fighting" may continue off and on between April and August as two or three broods are produced during that time.
The best solution is to break the reflection by covering the outside of the window. A plastic painter's drop cloth works well. The plastic is clear enough to allow light into the room, but cloudy enough to eliminate reflections. Other options are to soap the windows or put up screens or some newspaper.
Do not waste money on fake owls or rubber snakes, which reportedly frighten birds. The rival bird will still be visible in the window, and the territorial birds quickly learn that these artificial critters pose no threat.
